Interdimensional corridor
From Tardis Wiki, the free Doctor Who reference
Interdimensional corridors were energy vortexes, a method of crossing the dimensional divide to travel between the infinite number of dimensions that existed. They were a dazzling bright green in colour because of the interdimensional energy that flowed through them. They were created by the ancient Dimensioneers, though they began to degrade over the aeons. (AUDIO: UNIT: Dominion)
